4 Claims.

This invention relates to electric hair curling orwavingirons of the scissor type in which an oscilla-ting or vibrating leg operates in conjunction with a stationary leg to bring about the desired wave or curl in theV hair.

The primary object of the present invention is to provide a novel and eflicient hair waving iron of the above type having simple and eilici-ent meansfor rapidly vibrating `the oscillating leg and inwhichsaid means is mounted in and completely enclosed by a hollow handle of the stationary leg, said means being operatively conneoted to the handle of the vibrating leg within said handle of the stationary leg.

Another object of the present invention is to providesimple and eiicient means for manually swinging the vibrating legto and retaining the same in a position spacediroin the stationary leg to facilitate engagement of the hair with the iron or disengagement of the iron from the hair.

OtherA objects and features of the invention will become apparent from the following description ywhen considered in'connection-with the accompanyingdrawing,` and the invention consists in the noveliorm, combination and arrangement of, parts hereinafter more fully described, shown in the drawing and claimed.

, Inv the drawing, wherein like-reference characters indicate. corresponding parts'throughout the `several views:

Figure l is a substantially central longitudinal sectional View of a hair curling or waving iron constructedinaccordance 'with the present invention.v

Figurey2is a fragmentary longitudinal section taken substantially upon line 2-2 of Figure l.

Figure. 3 is a` transverse section taken on line 3+-3 of Figure 1.

Referring in detailto the drawing, the present electric-'vibrating hair curling or waving iron comprisesfa cylindrical vibrating leg 5 and a stationary trough-shaped leg 6 pivoted to each other in scissor-like fashion, as at l, the stationary leg 6 being provided with a relatively large elongated hollow handle 8 preferably formed of heat insulating and electrical insulatingT material. The forward portion of the handle has a longitudinal slot 9 in one side thereof within which is'v vibratable a shorter shank-like handle I0 of the vibrating leg 5.

suitablymounted at II within the inner portion of the'handle 8 is the coil l2 of a solenoid havinga core I3 reciprocable parallel with the longitudinal axisof` the waving iron, said core being normally projected forwardly by a spring I4 and being attractable rearwardly when the coil l2 is energized. Pivotally mounted at the juncture of its arms, as at l5, at the side of the handle opposite the slot 9 and in iront of the solenoid, is a bell'crank lever lli having a longer arm extending transversely of the handle 8 directly in front of the coil I2 and pivotally connected at il intermediate its ends with the forward end. of the core I3. The spring I4 is coiled about the pivot I5 of lever I6 and has one'end thereof bearing upon the handle 8 and the other end of the same engaged in a lug i8 provided on one side of the longer arm of lever I6. The other shorter arm of lever i6 extends forwardly from the pivot l5 and is operatively connected by a `connecting bar I9 with the inner end of the handle lil. Suitably mounted at lill directly in ront of the free end portion of the transverse longer arm of lever I6 is a normally closed circuit maker and breaker which includes a stationary contact 2l and a resilient flexible Contact 22,

the latter being arranged to be intermittently contacted by the longer arm of lever I5 as the latter is vlbrated by the reciprocation of solenoid core i3 for rapidly opening and closing the circuit oi the coil I2 by moving the contact 22 into engagement with contact 2| and then permitting .contact 22 to flex and disengage from said contact 2l. The contacts 2| and 22 are interposed in the circuit of the coil I2, as is also a manually operable switch 23 suitably mounted in one side of the handle 3. An adjusting screw 24 is arranged to impinge the free end of contact 22, and may be adjusted to effect a micromatic adjustment of contact 22 relative to the contact 2l so as to control the frequency of vibration of the solenoid core I3 and consequently of the vibrating leg 5 of the waving iron. At th'e inner end of the handle 8 there is provided an opening in which is swiveled a connector 25 to which the line wires `2li extend. Wires 2t connect contacts of this connector with the switch 23 and one side of the coil I2. The wires 25 may be those of an ordinary attachment cord adapted to be plugged into an outlet receptacle of an ordinary house wiring system so as to derive current for operation oi' the iron.

From the above description, it will be levident that the spring lll normally positions the lever I6 so that its longer arm positions contact 22 into engagement with contact 2| so as to close the circuit of the coil I2 at this point, Thus, when switch 23 is closed, the coil I2 is energized and the core I3 of the solenoid is caused to rapidly reciprocate ink accordance with well known principles of operation of electric vibrators. Such rapid reciprocation of core I3 causes rapid oscillation of lever I6 and, through connection I9 With handle IU, the leg 5 of the iron is rapidly vibrated. The use of a curling or Waving iron of this type is well known in the art, as well as its manner of use in bringing about the necessary Wave or curl in the hair,

If desired, the cylindrical vibrating leg 5 may be provided with an internal electrical heating element generally indicated by dotted lines at 2l, thereby avoiding the necessity of heating the leg 5 by an extraneous or outside source of heat. As shown, this electrical heating element may be connected with the wires 26 so as to derive current as soon as the attachment plug, of which the wires 26 form a part, is engaged in an outlet receptacle. Of course, a switch may be provided for controlling the flow of current from wires 26 to the heating element 2l if desired.

As shown clearly in Figure l, the shorter forwardly projecting arm of lever I6 is provided on its outer side with a cam lug 28, and slidably mounted in a slot 29 in the adjacent side of handle 8 is a iinffer piece or slide 3] having a ball or similar contact element 3| arranged to ride on the inclined surface of cam 28 when the slide 33 is shifted forwardly. The arrangement is such that when the slide 3G is shifted forwardly, the contact element 3| rides under the cam lug 28 so as to swing lever IE in a direction to actuate handle l0 and move the vibrating leg 5 to and retain the same in a position separated from the leg 6. When this is done, engagement of the hair with the iron or disengagement of the iron from the hair is facilitated, the switch 23 being of course turned off at this time. On the other hand', when the slide 30 is shifted rearwardly so as to move the Contact element 3| from beneath the cam lug 28, the lever I6 is free to be electrically vibra-ted by the solenoid when the switch 23 is turned on.

From the foregoing description, it will be seen that I have provided a very simple, compact, durable and ecient hair curling or waving arm of the type described which is convenient and easy to use, capable of being easily and cheaply manufactured and assembled, and otherwise well adapted to meet with the requirements for a successful commercial use. Minor changes in details of construction illustrated and described are contemplated, such as fairly fall within the spirit of the invention as claimed.
